While the device works fine, at the price we paid, I would expect a SIM card and a User Manual, neither of which were included.

Good concept, what I need in my rural area that doesn’t offer cable.
This modem will work fine for a while but the gets real slow. I have to reboot it to get my speeds back to normal. If I lose power or if power flickers, the modem uses its battery. Problem is when the power comes back on or after it flickers, the modem does not go back to using the AC power but instead, it keeps using it’s battery until dead. I have to unplug the modem, wait a little while then replug the modem to get it working off the AC again.

Short story long, this is our third such device, all IFWA-40. The first one, bought from the AT&T store did not work right out of the box. The wrong password was listed on the label. AT&T replaced it. The second worked for two years, 4 weeks, then it no longer connect with the cell tower, just 4 weeks out of warranty. A new SIM card did not fix the issue. Since these cannot be bought from AT&T anymore, or purchased new anywhere, I bought this refurbished unit from Amazon, popped in the SIM card and was off and running. However, the power cable supplied did not work. No output at all, nada, zip, dead as a door nail. The power cord from the old device had me up and running so all’s well. Plus, when I called Amazon about the defective power cord/battery charger, they gave me a HUGE Amazon store credit, many times what I expected. So I am a happy camper.

Now the down sides. First, this device has longevity issues. Out of three units, two had defects right out of the box, and the other one lasted until it was 4 weeks out of warranty. And none of them really connected well with our cell tower, which is located three miles away and I can see the light on the top of the tower easily at night. I only get one or two bars, tops, so when I bought this unit, I ordered the antenna set for it, hoping it would improve my signal. Now, don’t get me wrong, even with only one or two bars, the device works well even with streaming movies and our home telephone. But I would like a stronger signal so I bought the antennas. The external antenna did absolutely nothing to improve signal strength. Not with one attached, not with two attached, turned very wan and at every angle, so save your $12 on the external antenna.

On the BIG plus side, this unit is very easy to set up. Plug it in, turn it on, find the device on your computer, printers, ipad, iphone, blu-ray player, Direct TV box… type in the password and off you go. It handles up to 20 devices easily so even a dummy like me can set everything up in just a few minutes.

works well with my at&t
